TO ALL WHOM IT MAY CONCERN:

Be it known that JOHN R. WIIARItY, of Moundsville, in the county of'Marshall, and'kState of West Virginia, have invented a new and improvedVentilator' and Window-Screen; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, which willenable others skilled in the art to make and use the. same, referencebeing had -to the accompanying drawings, forming partei thisspecification.

This invention relates to an improved ventilator and window-screen, andconsists in afrume of wire netting, fitting beneath the outer and uppersash, and of a shutter having movable slats in front thereof, alsobeneath the said uppei sasl). In theacompcnying drawingsf Figure 1 is afront view of my improved ventilator and window-screen, and

Figure 2 is a vertical section thereof, at line :c x.

Similar ietters of reference indicate corresponding parts. i

A. is the upper sash, and B the lower, shownopen in the drawings. I" isa wire or metal nettingset in the frame G, beneath the upper or outersash A, wholly or partially filling up the space between said sash undwindow-sill, as maybe desired. f Secured to the `outside of said frameG, by thescrews gg, (which may be placed as shown in the drawings, or inthe sides, or in any other convenient placc,) is the shutter C C. Theupper part of the-*frame C being sloped to shed the-rain, andthe sidesrabbeted to it the outer bead-D, the centre bead may, it will" beobserved, be dispensed with. c c c are slats pivoted i-n the sides oi`frameC C', one end thereof being `conneeted by the metal bar e,w 1iieh,when operated by the lever F, opens or closes the ,slats simultaneously.The 1ever E wdrks through the slot .g in -frame G. Another anvd smallerscreen may, ifl

desired, be employed, either by itself, or with the frame'G, beneaththe' inner sash when open, the`spaee between the sides of screen-frameand the sash-frame being filled up byorie or more slats. This screen maybe secured to the-frame bya bolt or other approximate means; p

By the use of this screen,mosquitoes, illes, and other insects will bekept out of a room when the window is hoisted, notwithstandinga lightmay be burning therein. It will also help to keep out burglars or otherthieves, and enable the window to be left open when the house is quittcdfor a time, with thel advantage of finding the room sweet and pure onthe 'return of the inhabitants,

.As a useful'modification of the invention above described, the screenmight be inserted in the'shuttcr, and

the latter provided with a groove in each side, so as to slid'e up anddown a slat or bead fixed to the sides ofthe Window-frame, and ventilatoeither from the top or bottom of the window.

Having thus described my invention, what I claim as new, and des-iretogsecure by Letters Patent, isi-` 1. The combination ofthe wire screenand frame F Cr, shutters C C', and window-frame, as herein described.for the purpose specified.

2.` The'shutter C C', metalvbzir e, and lever E, substantially asdescribed, when disposed without the lower part of a window-frame,substantially as above set forth and described.

3'. The said shutter C C', in combination with the slot g', insereen-i`ramc G, substantially as above set forth und described. v l I'JOHN R. WHARRY.
